TILE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 298,002, dated May 6, 1884:.

Application filed August 11, 1883. (No model.)

which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved tile-machine. Fig. 2 is a plan View with the cover removed and ahorizontal section of the die-plate. Fig. 3 is a longitudinal section on the line 3 y of Fig. 1. Fig. 4 is a transverse section on the line a: x of Fig. 2 and w m of Fig. 3. Fig. 5 is a perspective view of the core over which the tiles are formed.

I arrange two hollow cylinders, a, side by' side in a suitable case consisting of bottom, I), and cover a, said cylinders being slightly tapered from the upper end, having the cover d to the other end discharging .into the dieplate 6, and they are separated by the partitionf. The die-plate has an orifice, g, out of which the tiles are delivered over the conical core h, on which the bore of the tiles is formed. This core is connected by its stem 13, placed in grooves of the partition f, which partition is partly formed in the two parts of the case, and meets together and closes on the stem when the case is closed. Said stem is notched at j, and the grooves are correspondingly formed for securely. holding the core against the pressure of the clay. The die- -plate is cup-shaped on the interior, to cause the two streams of clay to converge on the sides of the core, so as to be pressed firmly together to unite and form homogeneous connection.

end of the case by bolts k and flanges Z m, the holes in the flange Z being largerf than the bolts, to enable the die-plate to be shifted for adjusting it accurately to the core and for the application of die-plates and cores of different sizes for making tiles of different sizes. Each cylinder contains a screw or anger, n, to force The die-plate is connected to the the clay, and also to work it, said angers or screws being constructed in any approved form of the spirals and studs for working the clay, and having a' shaft, 0, extending out through the cap (1, wherein they have a bearing to be geared with the driving-pulley p.

The cover 0 has an opening through it at q, through which the clay is to be supplied to the machine. By employing two angers they may be made much smaller than when only one is.

used, and consequently will have much less resistance, both on'acconnt of their diminished size and of the division of the work. They will therefore have much greater strength proportionately to the work to bedone than when a single anger is used. The angers are sides of the forming-core is greatly facilitated by the collection of clay in the space at the end of the partition f, not directly in thelines of the stream, wherein is ample room for the merging of the two streams in one, so as to effect substantial connection and cause the rings thrown off by the angers to be smoothed and reduced to uniformity. The bearings of the auger-shafts in the caps d may be such that the angers n will be supported without contact withthe sides of the cylinders, if preferred.

I am aware that it is not new to use two plungers, screws, or angers in the same cylinder of a brick and tile machine; but

What I do claim as new and of my invention is- 1. The combination, with $0 plnngers, screws, or angers, of two cy 'nders, a a, divided by a partition closed at one end, open at the other, and provided a the open end with a cnpshaped die-plate, 6, open at g, and

a central conical core, h, as and for the purtwo sections forming cylinders a a, and pro- IO pose described. vided with an intermediate recess, half in each 2. The cylinder of a tile-machine, having section, and adapted to fit over said stem, as its internal diameter decreasing from the clayand for the purpose specified. 5 inlet to its outlet, to condense the clay as it ap- T proaches the die, and thus make a strong shell WARA ER LDXVIb' for the tile. \Vitnesses:
